North Atlantic Skies

Every day, between two and three thousand aircraft fly across the North Atlantic between Canada, the United States and Europe. Airspace across the North Atlantic is divided into six Oceanic Control Areas (or OCAs). These OCAs are controlled by Air Navigation Service Providers (ANSPs) working at different locations in different Countries. This visualization shows Transatlantic traffic over a 24 hour period taken from a day in August last year and shows 2,524 flights crossing the North Atlantic, of which 1,273 pass through the Shanwick OCA. At our busiest periods in the Summer, traffic can peak at 1,500 flights a day passing through the Shanwick OCA.
